There is no pressure threshold; typically it is referred to as a cyclone when there is a closed area of low pressure (as opposed to just a "wave").
It is a weather system in meteorology on the scale of a cyclone or anticyclone.
A cyclone has low pressure.
An extratropical cyclone is a synoptic scale low pressure system that is neither tropical nor polar. They often bring rain and thunderstorms. See the link below for more information.

The opposite of a cyclone is an anticyclone. A cyclone is a low-pressure system with inward spiraling winds, while an anticyclone is a high-pressure system with outward spiraling winds.

Low pressure.
Cyclone is caused due to the variation of atmospheric pressure in the air. Especially in the low atmospheric zone, air comes from all sides to balance the atmospheric pressure in that area. That's why cyclone is created. So the force for cyclone comes from variation in atmospheric pressure.
